SPECIFICATION forming part of Letters Patent No. 251,766, datedJanuary3, 1882.

' Application filedMarch 2|, 1881. (No model.)

To all whom it may concern Be it known that we, THOMAS A. UONLEE andJOHN H. KENNETH, residing at Dixon, in the county of Lee and State ofIllinois, and

5 citizens of the United States, have invented new and usefulImprovements in Sulky-Plow Lifting Devices, of which the following is afull description, reference being had to the accompanying drawings, inwhich wheel removed, showing the position of the lifting devices whenthe plow is in the ground; Fig. 2, a side elevation with thefurrow-wheel removed, showing the position of the lifting devices whenthe plow is raised "out of the ground; Fig. 3, a top or plan view withthe seat and tongue removed, the rear end of the plow-beam broken off,-and the lifting devices in the position shown in Fig. 1; Figs. 4, 5, and

6, details of the bars or links connecting the lifting-lever, crank orbail lifting arm, and the sliding catch or look which engages the wheel;Figs. 7 and 8, details of the stop for raising the sliding catch or lockand releasing it from engagement with the wheel; Fig. 9, a rearelevation with the plow removed; Fig. 10, a detail' showing theconstruction of the bell-crank levers for operating the lever-lock andthe slide or catch which engages with the wheel.

The object of this invention is to utilize the draft of the team inraising the plow out of the ground, and have the team lifting devicescombined and arranged with and having such relation to the hand liftingdevices that either 5 form of lift can be. used, as desired, without anychange of the parts, and without in any manner impairing theeffectiveness of either arrangement in use or interfering with thesuccessful operation of each as separate and dis- 4o tinct operatingdevices, so far as the method of lifting in each case is concerned, andhave the same locking arrangement, by which the plow is held either inthe ground or out ofthe ground, as required, common to both forms oflift, and operative with either in precisely the same manner so far. asthe lock is concerned,

. and so arranged with reference to the teamlift that it will beautomatically thrown into" Figure l is a side elevation with the furrowframe; 0, the swinging bail or crank; D, the

pivot-plate supporting the plow-beam; E, the plow-beam; E,- the plow; F,the lever for operating the leveling device of the land-wheel; G, thesegmental rack for holding the lever F; H, the forward or supportingbars or frame; 6 I, the foot-rest; J, the tongue-support; K, the platesto which the tongue is attached, and having slots by which its positioncan be changed for working two or three horses; L, the tongue;

These parts may beconstructed and arranged in any of the usual and well-known forms forthat class of sulky-plows in which the plow is carried by a crank orbail pivoted to the side pieces of an arch or frame, so that by raisingthe crank the plow can be suspended abovethe ground and by depressingthe crank it can be made to enter the ground. for the required depth ofplowing, and having the spindie of its land-wheel attached to the frameor arch, so that by means of the lever F and rack G the frame or archcan be raised or lowered 'to make the plow run level; but as these partsdo not constitute any part of the present invention, they need not befurther described, the invention relating simply to devices 'fonraisingthe crank and lifting the plow out of the ground, which devicesare constructed and arranged as follows:

N representsalifting-lever;O,the segmental 9o I rack; P, theconnecting-link between the lifting-lever and lifting-arm; Q, theprojection on the link P; R, the lifting-arm; S, the connection of thearm R with the bail or crank (J; a, the toothed or notched plate I), theteeth 5 or notches; c, the sliding arm or catch; d, the strap; 0, thelink for operating the 'arm 0; f, a connecting-rod; g, a.-hell-cranklever; h, a bell-crank lever; t, a point or projection on the lever h;i, an arm on the lever g; j, aeon- I00 necting-rod; 7r,alocking-pawl;l,a spring; m, a pin on the link P; m, a pin on the link 6; n, theprojecting end of the link 6; 0, the stop against which the end itstrikes; 1), the plate carrying the stop 0.

The parts constituting the lifting arrangement are arranged on thefurrow-wheel side of the machine, and the team-lift acts in conjunctionwith the furrow-wheel in liftingthe plow. These parts are entirelyindependent of the leveling devices on the opposite side of the frame.

end of which is pivoted-to the upper end of an arm, R, which arm isrigidly secured to acrosspiece, S, to the inner end of which is rigidlysecured the side arm or pivotal piece of the bail or crank C. Theseparts-the lever N, link P, and arm R-with the cross-piece or connectionS, constitute the hand-lift, the operation of which is as follows: Thedriver on the seat takes hold of the lever N and moves it either forwardto lower the crank and throw the plow into the ground or backward toraise the crank and hence lift the plow out of the ground, the forwardmovement of the lever causing its lower end to move backward, and,through the link P, giving a corresponding backward movement to the armll, which turns the cross-piece or connection S and lowers the crank D,thus lowering the plow, the backward movement of the lever causing itslower end to move forward and over the link P, giving a correspondingforward movement to the lifting-arm It, whichturns the cross-pieceorconnection S and raises the crank D, elevating the plow, the depth towhich the plow enters the ground being gaged by the point at which thelever is carried forward and locked. The connection or piece S is, infact, an extension of the spindle for the furrow-wheel, and the portionbetween its inner end and the spindle is left square, and on it adjacentto the plate a is located the lifting-arm R, the lower end of which hasa square opening to receive the connection or axle S and make a firmconnection between the arm and the axle. The inner end of thisconnection or axle S has a tenon or other form to enter a suitableopening or be otherwise connected rigidly with the ear or hanger onwhich is the pivot for the crank or bail, which pivot enters thevertical portion of the frame, as usual.

The arm or lever N is locked in whatever position it may be placed bymeans of a sliding pawl, 71', located on the lever, so that its point,when projected, will engage the notches of the rack, the pawl beingprojected by means of a suitable connecting-rod, j, one end of which isattached to the upper end of the pawl and the other to a bell-cranklever, h, pivoted to the lever N near its upper end.

The plate a is connected with the inner end of the hub of thefurrow-wheel by means of pins, or in any other suitable manner whichwill make the connection a rigid one; or this plate might be made a partof the hub, it so desired. On the periphery of this plate is a series ofnotches or teeth, b,one face of which is straight or tangential and theother curved or rounding. On the arm R, in a suitable support orhearing, is located an arm or catch, 0, which has a sliding movement upand down, so that its point can be made to engage the straight face ofthe notches or teeth I), or be left to clear such notches or teeth. Tothe upper end of this sliding arm or catch 0 is pivoted one end of astrap or bar, (I, the other end of which is pivoted to the rear end of alink, 6, which link is pivotally connected at or near its center, by'abolt or-otherwisc, with thelink P, the link P having a projection orstud,-Q, which forms a bearing for the pivoting-bolt, and also keeps thetwo links apart, so that the cannot become accidentally interlocked.

Near'the forward end of thelink e is pivoted one end of a rod,f, theother end of which is connectedwith the bell-crank lever 9, locatedbelow the bell-crank lever h on the lever N. The lever 9 passes bothsides of the lever N, and that side which is adjacent to the lever h isprovided with an arm or extension, '6, the end of which engages with thepoint or projection i on the lever h, so that the two levers will beinterlocked, and a movement of one will move the other-that is to say,if the lever g is depressed, the arm 4." will act on the point i andthrow the lever it up, and it the lever g be raised thearm i will act onthe pointt' and throw the lever h down.

The link 0, at its forward end, is slotted, and one portion is made toproject forward of the other and form an extension or arm, n, which, asthe arm R is carried forward, will come-in contact with the stop 0 on aplate, 1), which plate is attached to the side of the support K. Thisplatep is provided with a slot, by means of which the location of thestop 0 is kept adjusted, so that the arm n will come in contacttherewith when the arm R has raised the plow out of the ground.

Between the links 6 and P, and around the stud Q, is a spring, Z, onearm of which is connected with or engages a pin or catch, m, on thelinkP and the other is connected with or engages a pin or catch,'m', on thelink 0, so that the link 6, when the catch 0 is raised,will be heldinposition to prevent its rear end from vibrating accidentall y andthrowing the catch into engagement.

The operation is'as follows: When theplow is to be lifted through thepower of the team the driver takes hold of and depresses the lever g,which at the same time, through thearm t and point i, throws down thelever h, as before described, releasing the pawl is from engagement withthe rack O. The downward movement of the lever g, through the rod f,raises the forward end of the link eand depresses the rear end thereof,which, through the strap (7, projects the end of the arm or catch sothat it will be caught by one of thenotches b of the plate a, whichplate revolves with the wheel, and byits forward movement raises the armR, turning the cross-piece or connection S andlifting the crank G,raising the plow out of the ground. This forward movement will continueuntil the plow is raised, at which time the forward end or arm n of thelink 6 comes in contact with the stop 0, throwing the forward end of thelink down and raisingits rear end, and through the strap d lifting thecatch 0, and at the same time the downward movement of the forward endof the link e, through the rod f, depresses the lever g, and this lever,through its arm 13 and the point i, raises the lever h, whichvthrows thepawl 7c connected therewith into engagement with the rack O, and throughthe lever N holds the plow in its suspended position. By thisarrangement it will be seen that the driverisfree to use either form oflift, and that as lifting devices they are independent of each other,and at the same timeeither one can be operated readily.

The team lifting devices are very simple in construction, easilyoperated, and will do the work required in an effectual andreliablemanner, and in event that the party who uses the plow does notrequire or wish a team-lift the devices which constitute such lifts canbe removed without impairing orinjuring the hand-lift devices, which arenot changed or affected in any manner by such removal.

By making the plate p adjustable the stop 0 can be raised or lowered, sothat the end or arm 'n will come in contact therewith at the precisemovement required to release the catch 0 and throw the rack-pawl intoengagement, and that such adjustment enables any wear of the link 6 orother parts to be compensated for, so that such wear will not affect theproper working of the parts.

By making the levers g h interlock one with the other, one leversustains the other in whatbeing attached to the axle or cross-piece S,as

before described.

By releasing the catch 0 from the notches b automatically at the instantthe plow is raised to the extent of the elevation that is required itwill be seen that no straining of the parts will occur, and at the sametime the machine is left free to travel forward without interferencefrom the lifting devices. -2

When usingthe leverNasahand-leversimply the pawl or lock it canbereleased by the bellcrank lever it without affecting the bell-cranklever g, which will remain in position to keep the catch (3 disengaged;but the bell-crank lever 9 cannot be operated without atfecting thelever It.

. What we claim as new, and desire to secure by Letters Patent, is-- 1.The combination, with the crank O, of the notched plate 01, located onthe furrow-wheel hub, the sliding arm or catch 0, located on thelifting-arm R, the'strap or bar 01, the link 6, provided with anextension, n, the connecting-rod the bell-crank levers g hupou the armN, and the strap 0, for automaticallyraising the arm or catch when theas described. 7

2. The combination, with theliftin g-lever N, of the segmental rack O,the connecting-link P, arranged between the lifting-lever andliftingarm, and the lifting-arm the bail or crank connected with saidlifting-arm, the notched plate a, located on the furrow-wheel hub, thesliding arm or catch 0, thestrap d, link a, con necting-rodf, andbell-crank levers upon the lifting-lever N, said members being organizedfor operation substantially as described.
